Firewalls: What is the difference between Policy, NAT and Routes?
- by Jakobud
I'm learning fwbuilder and firewalls in general. I don't understand the differences between Policy, NAT and Routes. They all seem like they are just ways to tell the data where to go depending on what it is and where its coming from.
What is the real difference? Is a properly configured firewall taking advantage of all three (Policy, NAT and Routes) or are they just three different ways to accomplish the same thing and you only need one of them?
